Manufacturing Relationships, Distributing Quality
Release film that runs clean. Security film that leaves proof.
PROASP manufactures silicone-coated release films on metallised, polyester, HDPE and paper bases, and tamper-evident release films that make package interference visible — for packaging converters and security-sensitive supply chains.

Silicone-Coated Release Films
Silicone-coated metallised, polyester, HDPE and paper release films engineered for consistent release and stable converting across pressure-sensitive constructions.

Tamper-Evident Release Films
Security films that make interference visible — VOID transfer, dry-peel evidence and heat-sensitive Level 4 constructions.

Custom Development
Construction developed around your substrate, line speed, security requirement and finished format.
Longer runs. Fewer interruptions.
Run longer. Change less. Produce more.
A 24,000 m PROASP spool provides three times the running length of a conventional 8,000 m roll. For an equivalent production length, that can mean up to 66% fewer changeovers — helping reduce interruption, residual gum and LD-film waste while supporting higher line efficiency.
- Up to 66% fewer changeovers
- Less residual gum and LD-film waste
- Less machine downtime

Tamper-evident technology
Tampering should leave visible proof
Two signals, not one
A determined attempt on a sealed bag usually starts with a heat gun. Warm the seal, lift it slowly, close it again. Level 4 answers that directly: the heat is recorded whether or not the seal is successfully lifted, and lifting it transfers the message anyway. Defeating one signal does not defeat the other.
- Heat indicator
- Permanently changes from white to pink
- Removal evidence
- Transfers your message — VOID, STOP, TAMPERED BAG or your own wording
- Material
- 100% recyclable low-density polyethylene

STAGE 01
Sealed
The security film closes the bag. On a Level 4 construction the indicator stripe reads white.

STAGE 02
Heat exposes the attempt
Heat applied to the seal turns the indicator stripe pink. The change is permanent — cooling it does not turn it back.

STAGE 03
Lifting reveals the message
If the seal is lifted anyway, the layered construction transfers a permanent message across the separated layers.
The heat indicator is a Level 4 feature and is specified per application. It is not a property of every PROASP security film.
Manufacturing capability
From coating to finished product, under one roof
Silicone Coating
Solvent-based silicone coating applied in house, which keeps release level under direct process control.
Eight-Colour Gravure Printing
Eight-colour gravure printing for surface graphics, brand identification and custom security messaging.
VOID-to-TAMPERED Message Change
The transfer message is a specification, not a fixture — VOID, STOP, TAMPERED BAG or your own wording, changed between runs.
High-Speed Lamination
Lamination of multi-layer constructions, including the layered structures tamper evidence depends on.
High-Speed Slitting
Slitting and rewinding to the widths, lengths and core formats your line runs.
Spool and Pancake Winding
Extended-length winding in both formats, including the 24,000 m spool that carries three times a conventional roll.
